# MidiDeviceStatus

`public final class MidiDeviceStatus`
`extends Object` `implements Parcelable`

java.lang.Object
↳ | android.media.midi.MidiDeviceStatus

This is an immutable class that describes the current status of a MIDI device's ports.

## Summary

### Inherited constants
From interface `android.os.Parcelable`
`int` | `CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int` | `PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

### Fields
`public static final Creator<MidiDeviceStatus>` | `CREATOR`

### Public methods
`int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`MidiDeviceInfo` | `getDeviceInfo()` Returns the `MidiDeviceInfo` of the device.
`int` | `getOutputPortOpenCount(int portNumber)` Returns the number of clients currently connected to the specified output port.
`boolean` | `isInputPortOpen(int portNumber)` Returns true if an input port is open.
`String` | `toString()` Returns a string representation of the object.
`void` | `writeToParcel(Parcel parcel, int flags)` Flatten this object in to a Parcel.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
From interface `android.os.Parcelable`
`abstract int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void` | `writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

## Fields

### CREATOR

    public static final Creator<MidiDeviceStatus> CREATOR

## Public methods

### describeContents

    public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `writeToParcel(android.os.Parcel, int)`, the return value of this method must include the `CONTENTS_FILE_DESCRIPTOR` bit.

Returns
`int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

### getDeviceInfo

    public MidiDeviceInfo getDeviceInfo ()

Returns the `MidiDeviceInfo` of the device.

Returns
`MidiDeviceInfo` | the device info

### getOutputPortOpenCount

    public int getOutputPortOpenCount (int portNumber)

Returns the number of clients currently connected to the specified output port. Unlike input ports, an output port can be opened by multiple clients at the same time.

Parameters
`portNumber` | `int`: the output port's port number

Returns
`int` | output port open count

### isInputPortOpen

    public boolean isInputPortOpen (int portNumber)

Returns true if an input port is open. An input port can only be opened by one client at a time.

Parameters
`portNumber` | `int`: the input port's port number

Returns
`boolean` | input port open status

### toString

    public String toString ()

Returns a string representation of the object. In general, the `toString` method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The `toString` method for class `Object` returns a string consisting of the name of the class of which the object is an instance, the at-sign character ``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

>      getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel parcel,
                    int flags)

Flatten this object in to a Parcel.

Parameters
`parcel` | `Parcel`: The Parcel in which the object should be written.
`flags` | `int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
